Sponsor's own description

This was an interventional prospective randomized clinical trial (RCT) in parallel groups. The sample size is 32 patients who were randomly divided into two groups depending on the surgical intervention used. First group - patients underwent increasing the thickness of the mucous membrane using free connective tissue graft from tuberosity area of the upper jaw. Second group - patients used collagen matrix Fibro-Gide" (Geistlich Pharma AG, Bahnhofstrasse 40, 6110 Wolhusen, Switzerland; registration in Russia 19.08.2020 No FSZ -20207/11765). In the postoperative period the value of soft tissue thickness gain, severity of pain, collateral edema, amount of analgesics consumed, soft tissue aesthetics, keratinized mucosa width, quality of life and duration of surgery were assessed.
